Mbaka Area

Project Description

The Mbaka area is situated between Lake Nyasa and Mbeya town in SW Tanzania. It is a part of the northernmost sub-basin of the Nyasa rift at a triple junction of the East African rift. This area was recently studied mainly by numerous international research groups. The permeable intra-basin Mbaka fault and Livingstone border fault allow for the ascent of deep hot water and the Mbaka fault, especially, is characterized by linearly aligned hot springs. So far only preliminary conceptual models for the fault-hosted low-temperature geothermal systems (≥160°C) could be realised.

Therefore, GPT’s new surface exploration activities are focussed on the Mbaka area as a basis for a consistent conceptual model and for implementing the following development schedule:

Development Schedule

  • 2012/2013: Drilling of 600-800m deep exploration, production, and injection wells, testing of the reservoir; feasibility study
  • 2013/2014: Manufacturing and installation of pre-designed wellhead generators (consisting of <1 MW modules)
  • 2014/2015: Mbaka - Additional drilling (resource development); power plant design
  • 2016/2017: Replace wellhead generators with power plants of up to 10 MW capacity
